This expert panel discussion explores the current challenges in understanding and managing neuromyelitis optica spectrum disorder (NMOSD). Bringing together clinical perspectives, the conversation highlights gaps in pathophysiology, limitations in monitoring tools, and ongoing uncertainties in long-term treatment strategies. Despite advances in biomarkers and therapies, real-world decision-making remains largely driven by clinical experience.
Key Insights from the Lecture:
Antibodies alone are not sufficient to cause disease
Clinical context remains essential
T cells play a...
Neuromyelitis optica spectrum disorder (NMOSD) is a rare but severe relapsing disease of the central nervous system, characterized by attacks that lead to cumulative disability. Unlike multiple sclerosis, progression is not continuous but driven by relapses, making early diagnosis and rapid treatment essential. Advances in biomarkers, classification, and targeted therapies are reshaping how clinicians approach NMOSD management.
Key Insights from the Lecture:
NMOSD is a rare but globally variable disease
Disability is driven by relapses, not progression
Aquaporin-4 antibodies...
Nikolaos Grigoriadis presents a keynote lecture on the pathophysiology of Neuromyelitis Optica Spectrum Disorder (NMOSD), focusing on the immunological mechanisms underlying disease activity. The session provides clinically relevant insights into how these mechanisms translate into relapse patterns and therapeutic targets.
Key Insights from the Lecture:
NMOSD is a relapse-driven disease, with disability primarily resulting from acute attacks rather than progressive mechanisms
Anti-aquaporin-4 antibodies are present in the majority of patients and play a central pathogenic role...
Neuromyelitis optica spectrum disorder (NMOSD) is a rare but severe neuroinflammatory disease requiring rapid diagnosis and prompt treatment to prevent irreversible disability. In this expert-led webinar, Vincent van Pesch explores the latest advances in NMOSD diagnosis and management, with a particular focus on clinical practice in Belgium. The webinar is introduced and moderated by Melissa Cambron.
The session covers diagnostic red flags, imaging features, antibody testing, and evolving therapeutic strategies that are reshaping patient care.

Advances in antibody testing and biomarker-driven diagnostics have reshaped the distinction between Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorder (NMOSD), and MOG antibody-associated disease (MOGAD). Florian Deisenhammer reviews the historical shift from considering NMO a subtype of MS to recognizing NMOSD as a distinct antibody-mediated condition, and outlines how AQP4-IgG and MOG-IgG testing – together with characteristic MRI and CSF patterns – supports more accurate diagnosis. A central message is that these diseases can overlap clinically, but differ...
This lecture explains how antibody-mediated pathology translates into clinical phenotypes and treatment strategies in Neuromyelitis Optica Spectrum Disorder (NMOSD) and Myelin Oligodendrocyte Glycoprotein Antibody Disease (MOGAD). Melinda Magyari contrasts the core targets, astrocytes (aquaporin-4) in NMOSD versus myelin/oligodendrocytes (MOG) in MOGAD, and shows how these mechanisms drive differences in relapse recovery, long-term disability, and therapeutic priorities. A major emphasis is placed on early antibody testing to avoid misdiagnosis (particularly as Multiple Sclerosis) and...
